	There is a strong argument to be made for (re-)installing when
moving across a major version boundary.  Whan crossing more than
one, the case becomes even more formidable.
	And installing to a new disk allows you to use the old one as a
(hardware-enforced) read-only backup.
	The only two reasons I can think of for upgrading in place are
a) you cannot afford or have no access to a new disk or b) you
cannot make a reliable backup (which carries its own set of risks).
